I watch some British programs too, and it is not so much the accent as must as the different words and slang they use. We lived in Toronto for 12 years and got used to the "Eh?". It took us a while to get used to a friend calling a sofa a "chesterfield"!. She would refer to Detroit as Deetroyet. I grew up in New Joisy, went to university in Bahston for a couple of years. One day a food truck was out in front, I asked for a milkshake and got a beaten glass of milk, when I asked where the ice cream was, he said oh you want a frappe. I transferred to RIT is Rahchasta NY. Again it wasn't so much the accent as much as their unique pronunciations. There was an area Chili, but they they pronounced it Cheyeleye. When my sister-in-law moved to Florida, she sent us tongue in cheek book on understanding the southern accent. Like "my ahms are tarred" or there is "all" like "you all" or "all" that you put in your car. I guess living in so many different places, my accent has remained neutral, never had a Jersey accent because we were from a suburban area, not an industrial area like Newark or Perth Amboy.
